ABSTRACT:
Apparatus for mounting and aligning an optical element on a support structure comprises pivot means for mounting the element so that it can rotate about axes in two orthogonal directions and a pair of alignment means, each comprising a plunger and an inclined guide groove, for rotating the element about the two respective axes. Adjustment means, such as threaded screws, are provided for urging the plunger along the inclined grooves. The grooves are inclined at a sufficiently small angle to permit precision alignment. In order to reduce temperature sensitivity, the path of plunger motion is directed towards the pivotal centers and axes of the mount, and the optical element is placed on the axis between the pivot and the plunger.
